Thanks for the feedback! I'm not sure why you're encountering the issue, but at the very least we should do a better job displaying the error message.

 Issue 627182  has been merged into this issue.

 Issue 630943  has been merged into this issue.

VersionUpdaterWin::OnError expects to be able to put HTML markup in the error message. The new MD chrome://help page must support this. Thanks.

Displaying HTML error messages should work now. The error itself seems to be caused by the server (see description of the error code at https://cs.chromium.org/chromium/src/chrome/browser/google/google_update_win.h?l=31). I am marking this as fixed.
